What width does sheet vinyl come in?

In the UK, sheet vinyl typically comes in 2m, 3m and 4m roll widths. 4m is the most common and suits most rooms without seams. Narrower rolls (2m, 3m) are available for smaller spaces like bathrooms and kitchens. If your room is wider than the roll, a seam will be needed — a professional fitter can heat-weld or cold-weld vinyl seams. For a comparison with other floor coverings, see our Laminate Flooring Calculator (/flooring/laminate-flooring-calculator) or Carpet Calculator (/flooring/carpet-calculator).

What is LVT flooring and how is it sold?

LVT (Luxury Vinyl Tile) is a rigid or flexible vinyl flooring sold as individual tiles or planks that click together, similar to laminate. LVT is sold in packs covering 2.0-3.5 m² per pack depending on the brand. It is waterproof, durable and popular in kitchens and bathrooms. UK brands include Karndean, Amtico, Quick-Step and Harvey Maria. This vinyl flooring quantity calculator handles both sheet vinyl and LVT packs.

How much wastage should I allow for vinyl flooring?

Allow 10% wastage for standard rectangular rooms when ordering vinyl or LVT. For sheet vinyl in rooms wider than the roll width (requiring seams), increase to 15%. For LVT tiles and planks, 10% is usually sufficient for straight laying. Complex room shapes or diagonal patterns may need up to 15-20% extra. You can adjust the wastage percentage in this calculator.

Do I need underlay for vinyl flooring?

Sheet vinyl does not usually require separate underlay — it should be laid on a smooth, level subfloor. LVT click flooring may include built-in underlay or require a thin 1-1.5mm underlay designed for vinyl. Do not use thick carpet underlay under vinyl. If the subfloor is uneven, use our Self-Levelling Compound Calculator (/flooring/self-levelling-compound-calculator) to work out levelling quantities.

Can I lay vinyl flooring over tiles?

Yes, provided the existing tiles are firmly fixed, level and clean. Fill grout lines with a levelling compound if they are deeper than 1-2mm — otherwise they may show through the vinyl (known as telegraphing). Use our Floor Levelling Calculator (/flooring/floor-levelling-calculator) to estimate compound quantities. After laying vinyl, finish with skirting boards — see our Skirting Board Calculator (/flooring/skirting-board-calculator).

How We Calculate This

Our vinyl flooring calculator handles both sheet vinyl (sold off a roll by the metre) and LVT tiles/planks (sold in m² packs). For sheet vinyl, we factor in the roll width to calculate the actual length you need to buy.

Sheet vinyl formula

If room width ≤ roll width: Length to buy = Room length × (1 + Wastage %)

Area to buy = Length to buy × Roll width

LVT formula

Packs needed = (Room area × (1 + Wastage %)) ÷ Pack size (m²)

Standard UK sizes

Sheet vinyl rolls: 2m, 3m or 4m wide
LVT tile packs: Typically 2.0-3.34 m² per pack
LVT plank packs: Typically 2.0-3.0 m² per pack

Sheet vinyl is priced per m² or per linear metre from the roll. LVT is priced per pack or per m². Always check the specific pack size for your chosen product — it varies by brand and range.
